305-028-556-508

Edgeboard Connectors Overview

The EDAC 305-028-556-508 is a standard card edge connector featuring 28 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch with a row spacing of 3.56 mm (0.140 inch). Designed for vertical panel mounting, the connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current at temperatures ranging from -40°C to +105°C, it offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes against official EDAC documentation to confirm exact contact plating thickness and material specifications. Ensure that the receiving PCB design strictly adheres to the specified 1.57 mm thickness tolerance to guarantee proper mechanical engagement and electrical performance during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection with a 3.96 mm pitch is required for panel-mounted installations. The vertical orientation and specific board thickness compatibility distinguish it from surface-mount or single-row alternatives. Confirm that the operating temperature range and current rating align with the system's thermal and power management requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors for robust industrial environments. The series provides various position counts while maintaining consistent pitch and mounting characteristics. This specific model represents a mid-range position count option within the dual-row vertical mounting category.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-018-556-508 or 305-054-556-508 if position count adjustments are necessary. Verify that any substitute maintains the identical 3.96 mm pitch and 1.57 mm board thickness acceptance to ensure mechanical interchangeability.
